" If, however, a woman does not dare to receive, for great trepidation, she should be praised. "
Pope St Gregory the Great
“If however”. However what? He says women may do as they wish. There is no rule. Women are at liberty to do as they personally think right.
Does he say women who receive should not be praised, but rather be criticized for doing what he just said they may do?
While there is no dogma here, because none is necessary, the pope is establishing a universal practice or discipline in the Church. He did not say it is up to the local ordinary to decide what should take place in his territory. His statement plainly says it is up to the individual woman and what is implied in that is her mother or father, the parish priest, local bishops or any previous practice (tradition) here or there, is irrelevant to the matter. The local bishop, whatever his opinion might be, has no jurisdiction in the matter. The woman is at liberty.
If some Orthodox believe mothers and fathers, local clergy or past practice to the contrary take away this liberty of the individual they reject the practice made clear by this pope. That is not surprising, but their problem comes if their mothers, fathers, priests, bishops or local traditions are not in harmony with one another. What is permissable for an Orthodox woman here, is forbidden there.
In the end it is about bodily observance. A woman is not defiled by nature, made spiritually unclean, unfit to receive, to know and love God. She is welcome to receive her Lord and Savior. If what goes on in our bodies which we have no control over keeps us from the sacraments then our bodies make us unworthy. Then a dying person in the hospital leaking bodily fluids and blood and infection is unworthy of the things he needs most at the moment of death and prevented from receiving them.
This is certainly not what the Catholic Chuch teaches.
Long before the pope made the statement in question the issue was settled. Long before Catholics or Orthodox even thought about it, it was settled once and forever.
The woman with an issue of blood for many years who thought it made her unclean knew that if she approached Him and only touched his garment she would be healed. She did and she was, and Jesus Himself was pleased that she was set free. She thought it was forbidden for her to do this so she did it secretly. He did not rebuke her or send her away. Any religious leader or tradition that does the opposite disagrees with Christ Himself, not simply His spokesman. Are they judaizers? They seem to hold the same notions as the Jews about impurity, and women.
